Charmi cut a ribbon into 19 pieces . 7 of them are 11 cm each and the rest are 8 cm each . What was the length of the ribbon at first ?

a) 173 cm b) 183 cm c) 193 cm d) 165 cm ​

 Let original length of ribbon was x cm. Therefore,

➟ Length of ribbons of 11 cm = No. of pieces(11)

⟹ Total length = 7(11)

⟹ 77 cm....(1)

➼ Length of ribbons of 8 cm = No. of pieces(8)

⟹ Total length = 12(8)

⟹ 96 cm.....(2)

According to the question,

Original ribbon = Equation 1 + Equation 2

Hence, original length of ribbon at first was 173 cm. (Option a is correct)
